POWER RAIfiD-TRAVERSE AND FEED MOTION FOR mum.

Power Rapid-Traverse and Feed Motions for Planers, of which thefollowing description, inconnection with the accompanying drawings, is aspecification, like characters on the drawings representing like partsin each of the several views.

This invention relates to metal planers,

and particularly to those of larger sizes adapted for use on relativelyheavy and massive work. A principal object of the invention is toprovide connections whereby the tool saddles and tool holders may beoperated with a rapid traverse movement to bring them to operativeposition, and controlled by a relatively slower and separately actuatedfeed movement in the operation of the planer, and such connectionsequipped with controlling devices located at the saddle whereby thetraverse and feed movements of the tools may be controlled by anoperator from the locality of the saddle, and there being preferablyprovision whereby such control may also be effected from the side of themachine if desired. The foregoing and other objects and advantages ofthe in vention will more fully appear from the following detaileddescription, and the dis-. tinctive features of novelty will bethereafter pointed out in the appended claims.

dles 7, 8, and as'shown these uprights are also equipped with side toolheads 9. Itis ,dsirableand important that provision be made whereby theoperator may control the rapid traversing and also the operativemovements of the tools from'a point adjacent thereto so that hemay havethework under close observation in the manipulation of the tools and thepresent invention provides means whereby tliiscontrol may be effected ina convenient manner from either saddle. Power for the rapid traversemovements of the saddles and tool holders is derived from 'a motor 10mounted on the top rail 5 which through reducing gearing 11' drivesconstantly a short shaft 12 journaled on the top rail intermediate itslength. The shaft 12 has loosely fitted thereon spaced apart pinions 13,1 1 which are selectively. engageable with saidshaft by a double endedfriction clutch slidably fitted on the shaft. The gear 13 engages anddrives a gear 16 fixed on a shaft'17 horizontally journaled on the toprail and extending-the entire distance between the uprights. The shaft17 also has a gear 18 fixed thereon which maybe driven from the gear 1 1in a reverse direction relative to the-drive of the gear 16 by means ofan intermediate gear 19. The shaft 17 through bevel gears 20 drives ashaft 21 vertically journaled at the end of the upright 4 and extendingdownward to the base thereof. The'shaft 21 has slidably keyed thereonabevel pinion22 which operatively engages a bevel gear 23 fixed at theinner end of a short shaft 2 1j0urnaled in a'bracket 25 of the crossrail, the pinion 22 being also held to travel with the cross rail and toremain in mesh with the gear 23. The shaft 24 has fixed at its outer enda "pinion 26 which engages a relatively large gear 27 loosely journaledon a short shaft 28 fixed in the end of the cross .rail, The gear 27engages a series of pinions 29, 30, 31 loosely mounted on end portionsof the feed screws 32, 33 and the feed shaft 34 respectively, the feedscrews being adapted for operating the respective saddles along thecross rail and the feedshaft 34 for imparting vertical movement to thetool holders on the saddles pinions 29, 30, 31 are equipped at theirouter sides with clutch faces 35 which are engageable by cooperativefaces 36 at one end of clutch hubs 37 slidably keyed on the respec- 1 05in accordancewith the usual practice. The

tive shafts 32, 33, 34. These clutch hubs are operated by shifters 38borne by shafts 39 extending to the outside of the housing and equippedwith handles 40. For controlling this rapid traverse movement so as toengage it in either direction or to disengage it, the double yfrictionclutch hub 15. is equipped with an arm 41 having connected thereto a rod42 which extends to the side of the machine where it is engaged with acrank 43 fixed at the upper end of a rock shaft 44 vertically journaledto bracket bearings of the upright. This rock shaft 44 has fixed to alower end portion thereof a handle 45 whereby it may be actuated from aposition adjacent the upright. F or operating this rock shaft and thuscontrolling the rapid traverse from either of the saddles, this shaft 44has slidably keyed thereto a bevel pinion 46 which is journaled in, andheld from endwise movement by a sleeve 47 in the end of the cross rail.This pinion engages a bevel pinion 48 fixed on a short shaft 49horizontally journaled at the end of the cross rail. The shaft 49 hasfixed to its other end an arm 50 the outer end of which engages with alink 51. The other end of the link 51 is pivoted to the outer end of anarm 52 fixed toa rock shaft 53 which is horizontally journaled in thecross rail and extends the length thereof. The shaft 53 has slidablykeyed thereon bevel pinions 54, there being one thereof journaled atside of each saddle and held to travel therewith. Each of these pinions54 is engaged by a bevel pinion 55 ournaled in the saddle and havingrigid therewith a handle 56 extending at the front of one side ofthesaddle. Thus by operating either of these handles 56 at either of thesaddles on the cross rail, the rapid traverse for either direction ofmovement may be thrown into engagement or disconnected at will. Forimparting feed movement to the feed screws andshafts 32, 33, 34, poweris taken from a shaft 57 vertically journaled alongside the upright 4and oscillated from a feedbox (not shown) at the base of the machinein-usual manner on each stroke of the table. The shaft 57 has slidablykeyed thereon and carried by the cross rail a bevel pinion 58 whichmeshes with a pinion 59 xed at the inner end of a short shaft 60journaledin bearings at thevouter end of the'cross rail. The shaft 60has'fixed at its outer extremity a feed block 61 having a linkconnection 62 to a crank pin 63 borne by a driving bar member 64 of aclutch device adapted to engage a relatively large gear 65 looselyjournaled on the shaft 28. To effect this clutch connection the clutchbar member 64 is loosely journaled on a hub 65 of the coiiperative tofrictionally engage an internal clutch surface 65 of the gear 65. .Therock shaft 66 has fixed at its inner'end an arm 69 constituting a clutchfinger andhaving at its inner end a pin 69 engaged by a cone 70 slidableon a reduced extension of the gear hub 65 The cone 7 O is engaged by ashipper yoke 71 pivoted at 72 to a bracket 73 borne by the cross rail.This shipper yoke has a downward extension past its pivot which bears apin 74 engaging in a cam slot 75 formed in a cam head 76 which is fixedto a short rockshaft 77 horizontally j ournaled at the end portion ofthe cross rail. The shaft? 7 has fixed thereto an arm' 78,

the outer end of which is engaged with a link bar 79, the other end ofwhich engages an arm 80 fixed to a shaft 81 horizontally journaled inthe cross rail and extendingthe j The shaft 81 hasslidably for movementtherewith. Each pinion 82 meshes with a coiiperative pinion 83 journaledin a bracket of the saddle and having a handle 84 rigid therewith, thesehandles 84 preferably and as shown, being located on the same side ofthe saddle as the handles 56 and in the present embodiment beingdirectly thereover. Thus by manipulating a handle 84 at either saddlethe gear 65 may be thrown into engagement with the oscillating feedmovementfor transmitting the same to the feed screws and shafts.transmission from the gear 65 to the feed screws and shaft when the feedis to be employed, is effected through pinions 85 loosely mounted on theends of the respective shafts 32, 33, 34. These pinions may be formedin- I ,teriorly as click boxes (not shown) in. ac-

This 3 a clutch face 36 on the end of the clutch i hub 37 coeperateswhen said clutch hub is thrown to the right as seen in Fig. 4. Thus byadjusting the clutch hub 37 on either of the feed shafts 32, 33, 34 tothe right (Fig. 4), a step-by-step feed movement at a rela tively slowrate may be transmitted, to actuate either of the cross rail'saddles ortool holders when the upper handle 84 of such saddle is moved to engagethe feed. Likewise with a clutch hub 37 adjusted to the left (Fig. 4)the power rapid traverse may be engaged for either saddleupon actuationof the lower handle46 o'nisuch saddle, it being noted that there is thusno possibility of the feed and rapid traverse to any feed shaft beingengaged at the sametime, and

when the clutch hub 37 is in intermediate position both the feed andrapid traverse are the foregoing description to indicate the scope ofthe invention.
